Using Let’s Encrypt and Certbot to automate the creation of certificates for OpenVPN

Recently at Planet 9 Energy, I had to setup a VPN access to secure some of our internal services. One of the requirements was to make the provisioning easy to reproduce over multiple environments, so we ended up playing a bit with Terraform, while obviously adopting OpenVPN for the VPN server. Another important requirement was to expose the OpenVPN web interface (also called Access Server) using an SSL, which I was expecting to be one of the most challenging things to automate, instead, it turned out to be…

My Serverless talk at Shift conference in Split

This June, I had an amazing experience talking again about Serverless and how we use it at Planet 9 Energy at the recent Shift Conference in Split, Croatia. In my talk titled ”Serverless: The pros and cons of building a company without infrastructure”, I tried to address what Serverless is and why is becoming such a big thing, also exploring what I believe are the pros and cons of this new paradigm. The experience was great and I was super happy to have a chance to share the stage with extraordinary people…

My Universal JavaScript Web Applications talk at Codemotion Rome 2017

Last month (March 25th) I had the pleasure of delivering again my Universal JavaScript talk in a Codemotion Event, this time in Rome.

Judo Heroes Version 2 For this occasion, I updated my common Universal JavaScript Judo Heroes to ”Version 2“. I believe this new version looks a bit more polished and easy to understand, plus it features a number of other relevant…

Unshorten (expand) short URLs with Node.js

Short URLs have been an invaluable tool for social media marketing for so many years and we are now used to seeing them everywhere. Most of the credit probably goes to URL shorteners services like Bit.ly, Goo.gl, YOURLS and Rebrandly that popularised the concept and made easy for everyone to start creating short URLs. When working with URLs in some automation scenarios like analytics, information crawling, data retrieval, etc. it can be important to resolve (or ”unshorten” or ”expand”) short URLs, which…

My Serverless & AWS Lambda talk at Node.js Dublin January 2017

Last January I had the pleasure to share the stage with the great Padraig O’Brien to talk about how we use Node.js, AWS Lambda and the Serverless framework at Planet9 Energy. The talk was hosted by the monthly Node.js Dublin Meetup at Intercom Dublin office, as usual, a very cool location for this kind of tech talks. Apart from having a great chance to show off my über cool Super Mario T-shirt for about 45 minutes, Podge and I had some good time discussing the following topics: What does ”Serverless” mean…

2016 - A year in review

2016 is almost over and I just realised that it has been one of my most productive and exciting years ever. With that in mind I would love to write a recap of all the good and bad things (mostly from a career perspective) that happened in my life during this year. I want to keep track and benchmark my productivity over the coming years. This might be boring for you to read but I hope it’s going to serve myself as a good motivation to keep doing better over the years, both in terms of career and quality of…

How to crack a JWT token: two articles about distributed computing, ZeroMQ & Node.js

In the last 2 weeks I add the pleasure to release an article (in two parts) in collaboration with RisingStack, one of the most famous companies in the Node.js ecosystem. The article explains how to build a distributed application using Node.js and ZeroMQ and provides an example that I believe it’s very actual and interesting: a JWT token cracker. If you are into Node.js, ZeroMQ, security or distributed application you can read the two articles in the community section of RisingStack. ZeroMQ & Node.js…

React on the Server for Beginners: Build a Universal React and Node App

I recently wrote a new article in collaboration with one of my favourite web development websites: the amazing Scotch.io. The article talk about using React both on client and on the server (with Node.js) in an attempt to build a simple “Universal JavaScript” (a.k.a “Isomorphic”) application. The application is called “Judo Heroes” (did you even noticed recently that I’m kind of fond of Judo?) and it showcases some of the best Judo athletes for their number of medals won during the Olympic Games and in…
